HIG H-PRESSU RE BALL-COCK.

SPECIFICATION forming part of Letters Patent No. 719,447, dated February3, 1903.

Application filed May 1'7, 1902. Serial No. 107,806. (No model.)

To (oZZ whom it may concern:

Be it known that I, OSCAR JULIUS FABIAN, a citizen of the UnitedStates,residing at Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented a new and useful High-Pressure Ball-Cock,of which the following is a specification.

This invention relates generally to floatvalves, and more particularlyto one particularly adapted for use in connection with high pressures.

The object of the invention is to provide a simple and highly-efficientconstruction of valve-operating means particularly useful in connectionwith tanks and so constructed that the valve can be operated at anydesired point, and another object is to provide a valve-operating meansof such construction thit the float can be arranged upon either s1 e.

With these objects in view the invention consists in the novel featuresof construction and combination, all of which will be fullydescribedhereinafter and pointed out in the claim.

In the drawings forming a part of this specification, Figure l is a Viewshowing a valve constructed in accordance with my invention. Fig. 2 is asectional view showing the valve open. Fig. 3 is a sectional viewshowing the valve closed, and Fig. 4 is a detail top plan view.

Inasmuch as my invention is particularly useful in connection withtanks, I have shown an ordinary water-tank A and likewise an ordinaryfloat B, having an arm B connected thereto.

0 indicates the water-supply pipe, which projects up through the bottomof the tank, is slightly contracted at its upper end, and terminates ina valve-seat C. Suitable pack ing collars and gaskets D are employed forefiecting a tight joint between the pipe and tank. The valve-casing E issecured upon the top of the pipe 0 and is provided with adischarge-outlet E.

F indicates the valve, having a stem G, which projects up through thetop of the case, said valve being preferably provided with a rubber faceF, which is adapted to seat firmly upon the seat 0. The valve-stem G ispreferably rectangular in cross-section and has'its opposite faceprovided with rack-teeth G. The valve-casing is provided with parallelears II, and between one set of ears is journaled a pinion I, whichmeshes with the rack-teeth G, adjacent thereto, and between the otherpair of ears is pivoted the arm K, having the pinion L integral with itsinner end, the outer end being shaped into a socket M to receive the endof the rod B.

From the construction herein shown and described it is obvious that asthe tank fills with Water the float will be raised, and as the floatrises it carries with it the rod B, and the arm K is consequentlyelevated, and the pinion L, meshing with the rack-teeth of thevalve-stem, forces the said valve-stem and valve downwardly and sets thevalve firmly upon the seat C.

When'the water escapes from the tank, the float of course drops, and thevalve-stem is elevated through the medium of the arm K and pinion L. Thepinion I upon the opposite side serves to guide a steady movement of thevalve-stem. It is obvious that gears I and L are interchangeable, sothat the fioat can be arranged upon either side of the valve, and,furthermore,,the pinion L can be so adj ustcd with reference to therack-bar that the valve can be opened and closed at any desired point.

It will thus be seen that I provide an exceedingly simple constructionof valve and operating mechanism connected therewith, and it will alsobe understood that the device is particularly useful in connection withlarge tanks and also for connection with high-pressuresupply-pipes,inasmuch as the gearing parts positively hold the valveeither in an open or closed position, and, furthermore,the movement ofthe float positively operates the valve and its. stem through the mediumof the gearing devices. It will also be understood that for very largetanks and valves I may employ two levers, one upon each side of thevalve-stem, each one carrying a float at its outer end.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

The combination with a supply-pipe terminating in a valve-seat, of avalve-casing arranged upon the upper end of the pipe and provided with adischarge-outlet, said valvecasing also having a stem-guide and parallelears, the Valve arranged within the casing and having a stem projectingupwardly therefrom, said stern having rack-teeth upon its oppositesides, a pinion pivoted between one pair of ears and engaging therack-teeth upon one side, .an arm having a pinion integral therewith andpivoted between the other pair of ears and engaging the rack-teeth, andthe 10 float having its rod connected to the arm, for

the purpose specified.

OSCAR JULIUS FABIAN.
